Bio-lipid, which is renewable and alternatives energy resource, has potential converted into biofuels such as biodiesel. It use can contribute to reducing carbon dioxide emissions, potential depletion of fossil-fuel reservoirs and risk of energy price crisis. Various lipid sources for biodiesel production include vegetable and animal oil. However, traditional oils are limited nowadays owing to the food versus fuel and dramatically increase energy demands. Bio-lipid from oleaginous yeast is appropriate as an ideal source for biodiesel production because of its fast growth and high production. Lipid production by oleaginous yeast can be used as various carbon sources such as glucose, sucrose, molasses, glycerol, and volatile fatty acid. Especially, acetate, one of a variety of volatile fatty acids, can be used precursor for lipid synthesis metabolism and Acetyl-CoA, which can be converted from acetate, is intermediate for synthesis of polyunsaturated fatty acids and lipid production. Under nitrogen limited conditions, acetate can be reasonable carbon source for lipid production by oleaginous yeast. Our research teams conduct to comparatively comprehensive screening for isolation of acetate-utilizing and high-oleaginous yeast from Korean rice wine.
